FIRE AND BURN HAZARD
NOTES:
1. Follow these instructions and those published by the battery
manufacturer and the manufacturer of any equipment you intend to use
in the vicinity of the battery. Review cautionary markings on these
products and on the engine.
2. This inverter/charger contains components which tend to produce arcs
or sparks.
3. Locations include any space containing gasoline-powered machinery,
fuel tanks, as well as joints, fittings, or other connections between
components of the fuel system.
Precautions When Working With Batteries
5.
BURN FROM HIGH SHORT-CIRCUIT CURRENT, FIRE AND EXPLOSION FROM VENTED GASES HAZARDS
•
•
•
•
Always wear proper, non-absorbent gloves, complete eye protection,
and clothing protection. Avoid touching your eyes and wiping your
forehead while working near batteries. See note #4.
Remove all personal metal items, like rings, bracelets, and watches
when working with batteries. See notes #5 and #6 below.
Never smoke or allow a spark or flame near the engine or batteries.
Never charge a frozen battery.
6.
7.
Use extra caution to reduce the risk or dropping a metal tool on the
battery. It could spark or short circuit the battery or other electrical
parts and could cause an explosion.
Batteries can produce a short circuit current high enough to weld a ring
or metal bracelet or the like to the battery terminal, causing a severe
burn.
When removing a battery, always remove the negative terminal from
the battery first for systems with grounded negative. If it is grounded
positive, remove the positive terminal first. Make sure all loads
connected to the battery and all accessories are off so you don’t cause
an arc.
injury.
NOTES:
1. Mount and place the Freedom SW 3000 Inverter/Charger unit away
from batteries in a well ventilated compartment.
2. Always have someone within range of your voice or close enough to
come to your aid when you work near a lead-acid battery.
3. Always have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing, or eyes.
4. If battery acid contacts skin or clothing, wash immediately with soap
and water. If acid enters your eye, immediately flood it with running
cold water for at least twenty minutes and get medical attention
immediately.
vi
Precautions When Placing the Inverter/Charger
EXPOSURE TO CHEMICALS AND GASES HAZARD
RISK OF DAMAGE TO THE INVERTER/CHARGER
•
•
•
•
Make sure the area around the battery is well ventilated.
Make sure the voltage of the batteries matches the output voltage of
the inverter/charger.
Be careful to keep corrosion from coming into contact with your eyes
and skin when cleaning battery terminals.
injury.
•
•
Never allow battery acid to drip on the inverter/charger when reading
gravity, or filling battery.
Never place the Freedom SW 3000 Inverter/Charger unit directly
above batteries; gases from a battery will corrode and damage the
inverter/charger.
Do not place a battery on top of the inverter/charger.
NOTES:
•
Study and follow all of the battery manufacturer's specific precautions,
such as removing or not removing cell caps while charging, whether
equalization is acceptable for your battery, and recommended rates of
charge.
•
For flooded non-sealed batteries, add distilled water in each cell until
battery acid reaches the level specified by the battery manufacturer.
This helps to purge excessive gas from cells. Do not overfill. For a
battery without removable cell caps, carefully follow manufacturer's
instructions.

Planning the Installation
This section provides information to help you plan for a basic installation of
the Freedom SW 3000.
Two Key Performance Factors
As your system configuration is determined, record the details in
Information About Your System of the Freedom SW 3000 Sine Wave
Inverter/Charger Owner’s Guide.
Two key factors in particular will have a major impact on system
performance.
Size and Length of DC Cables
To select the appropriate size and length of DC cables, see “DC Cabling” on
page 13.
The DC cables should be as short as possible and large enough to handle the
required current, in accordance with the electrical codes or regulations
applicable to your installation. If there are long battery cables which are in
excess of 10 feet each and not of sufficient size, the voltage drop across the
cables will have a negative impact on overall system performance.
Mounting Location of the Freedom SW 3000
To choose an appropriate location for mounting the inverter/charger, see
“Step 1: Choosing a Location for the Inverter/Charger” on page 18.

AC Components
AC Input
AC input to the Freedom SW 3000 can be supplied from a split-phase or
dual-input AC source such as the utility grid (power company), a generator,
or the output of a transfer switch. The Freedom SW 3000 can be operated
from the following types of 120 volt 60 Hz AC sources:
•
•
Split phase: This source type has two lines, one neutral, and one
ground. The two 120 VAC lines are 180 degrees out of phase with each
other, so that the two voltages total to 240 VAC. The voltage between
each line and neutral is still 120 VAC, and the voltage between the
neutral and ground is approximately zero.
Because the two lines are out of phase, the currents from each line
subtract in the neutral, and the neutral current will be approximately
zero if the loads are equal. For example, if Line 1 is supplying 20A and
Line 2 is supplying 15A, the current in the neutral will be 5A.
Dual input: This source type has two line inputs, one neutral, and one
ground. Unlike the split-phase type, the two lines are in phase (not out
of phase), and must come from the same source. The voltage between
the two lines is zero. The voltage between each line and the neutral is
120 VAC, and the voltage between the neutral and ground is
approximately zero.
Because the two lines are in phase, the currents from each line add
together in the neutral. For example, if Line 1 is supplying 20A and
Line 2 is supplying 15A, the current in the neutral will be 35A.
975-0546-01-01
IMPORTANT: The Freedom SW 3000 is designed to be connected to AC
sources that energize both L1 and L2 inputs, and cannot be powered by
single-phase input where only one of L1 or L2 is energized. To connect the
Freedom SW 3000 to a single-phase AC supply, install an appropriate
transfer switch to energize both L1 and L2 inputs. Consult a qualified
installer for further support.
AC Output
AC output from the Freedom SW 3000 is 120 VAC, and can be wired as
single output or dual output.
AC Loads
The Freedom SW 3000 is intended to power loads consisting of 120 VAC
appliances.
In Invert mode, the Freedom SW 3000 connects L1 and L2 output lines
together to provide 120 VAC to loads on either line. In AC Bypass mode,
the source connected to the AC input is passed through to the load. Because
of the way invert mode operates, only 120 VAC appliances can be
connected to the Freedom SW 3000 output.
Do not connect 240 VAC loads to the Freedom SW 3000 outputs. Doing
so may result in 120 VAC on exposed parts of the appliance.
injury.

Planning
Planning
AC Disconnect and Over-Current Protection Device
To meet CSA, UL, and electrical code requirements, and to protect system
wiring, the AC inputs and outputs of the inverter/charger must be provided
with over-current protection on both the AC input and output. This
protection may be a circuit breaker or a fuse with a disconnect device (for
simplicity the following refers to breakers). Refer to your applicable
installation codes and the following requirements:
GFCI Requirements
A GFCI (ground fault circuit interrupter) is a device that deenergizes a
circuit when a current to ground exceeds a specified value that is less than
that required to open the circuit breaker. GFCIs are intended to protect
people from electric shocks and are usually required in wet or damp
locations.
Installation in recreational vehicles requires GFCI protection of certain
branch circuits. Consult all applicable codes.
AC Input Protection
Tested GFCIs
The breakers protecting the AC input of the Freedom SW 3000 must be
approved for use on 120 VAC branch circuits, and must be located in each
Line. The breakers must be rated as shown below:
Compliance with UL standards requires that Xantrex test and recommend
specific GFCIs for use on the output of the inverter. Table 1 lists models
that have been tested and will function properly when connected to the AC
output of the Freedom SW 3000.
•
•
Split-phase input: No more than 30 amps max in each line.
Dual input: The neutral current in a dual-input system is the sum of the
two line currents, and must be limited to 60A maximum to protect the
transfer relay in the Freedom SW 3000. Each breaker must not exceed
30A, and the total (sum) of the ratings of the two breakers must not
exceed 60A.
AC Output Protection
The breaker between the Freedom SW 3000 AC output and the AC loads
must be rated to protect the AC output wire size used. If the AC output
wiring is based on the full 30A pass-through rating, then a 30A output
breaker is acceptable. If the AC output wiring is smaller, then the breaker
size will have to be smaller as well, in accordance with applicable electrical
installation codes.

Disconnect Devices
Each system requires a method of disconnecting the AC circuits. If the
over-current protection device is a circuit breaker, it will also serve as the
disconnect. If fuses are used, separate AC disconnect switches will be
needed between the source and the fuses.
Planning
Distribution Panels
Size of AC Input Wiring Wire size must be coordinated with the
overcurrent protection provided ahead of the wire involved, in accordance
with the electrical codes or regulations applicable to your installation.
Therefore, the wiring used between the AC input circuit breaker and the
inverter/charger input must be sized to match the input breaker rating.
Table 2 AC Wire Size In and Out of the Inverter/Charger
AC Wiring
Definition AC wiring includes input wiring (all the wires and connectors
between the AC source and the inverter/charger input) and output wiring
(all the wires between the inverter/charger and the AC load panels, circuit
breakers, and loads).
Type The type of wiring required varies according to the electrical codes
or regulations applicable to your installation. For RV applications, this may
be solid wire in multi-conductor cables, but stranded wire is required if
single conductors are used. All wiring must be rated 90 °C or higher.

Size of AC Output Wiring Wire size must be coordinated with the
current the wiring will carry. This current may be determined by the 25 A
maximum inverter current, or by the bypass current, which is determined by
the overcurrent protection provided ahead of the Freedom SW 3000.
•
975-0546-01-01
If the input wiring is split-phase, the output wiring must be sized to
coordinate with the breakers used on the input. Refer to your
applicable installation codes.
11
Some systems incorporate distribution panels both ahead of the inverter/
charger (the AC source panel) and between the inverter/charger and the
loads (the AC load panel). The AC source panel includes a main circuit
breaker, which serves as over-current protection for the panel. Additional
circuit breakers serve individual circuits, one of which serves the inverter/
charger.
Planning
•
If the input wiring is dual-input and the output wiring is single-input,
the following rules apply: If the input breaker on L1 is greater than 25
A, the wire size must be coordinated for that amperage. If the input
breaker on L1 is less than 25 A, the wire size must be coordinated for
25 A. The wire size must not be sized for anything lower than 25 A.
•
If both the input and the output wiring are dual-input, the output wiring
for each line (L1 and L2) must be calculated separately, following
these rules: If the input breaker on the specific line is greater than 25
A, the wire size for that line and its neutral must be coordinated for
that amperage. If the input breaker on the specific line is less than 25
A, the wire size for that line and its neutral must be coordinated for 25
A. The wire size must not be sized for anything lower than 25 A.
Size of Wiring Downstream of the AC Output Breaker The wiring
used between the AC output breaker and your loads must be sized to match
the output breaker.
12
AC Output Neutral Bonding
The AC source must have its neutral conductor bonded to ground.
Bonding system The Freedom SW 3000 provides a system that
automatically connects the neutral conductor of the inverter’s AC output
circuit to safety ground (“bonding” it) while the inverter/charger is
inverting, and disconnects it (“unbonding” it) when the inverter/charger is
connected to external AC power. This system is designed to conform to
installation codes that require AC sources such as inverters and generators
to have their neutral conductors tied to ground at the source of power in the
same way that the neutral conductor from the utility is tied to ground. These
same codes specify that the neutral can only be connected to ground in one
place at any one time.
Suitability This automatic neutral-to-ground bonding system requires AC
input sources with bonded neutral. This will be the case in most situations:
in a utility feed, at an external AC hook-up, or a generator with a bonded
neutral. If not, have an electrician look into bonding the source’s neutral to
ground. See also “AC Input and Output Isolation” on page 23.
Planning
DC Components
The Freedom SW 3000 system requires a 12 volt, lead-acid deep-cycle
battery or group of batteries to provide the DC current that the inverter/
charger converts to AC power. The battery may be a flooded, gel, or AGM
type.

Restrictions on the size of appliances.
For information on cabling and hooking up batteries, see “Cabling and
Hook-up Configurations” on page 45.
For detailed information about specific brands of batteries, you’ll need to
consult individual battery manufacturers for this information.
DC Disconnects and Over-Current Devices
The DC circuit from the battery to the inverter/charger must be equipped
with a disconnect and over-current protection device. (Refer to your
applicable installation code.)
Type This device usually consists of a circuit breaker, a “fuseddisconnect,” or a separate fuse and DC disconnect. Do not confuse AC
circuit breakers with DC circuit breakers. They are not interchangeable.
Rating The rating of the fuse or breaker must be matched to the size of
cables used in accordance with the applicable installation codes.
975-0546-01-01
Location The breaker or fuse and disconnect should be located as close
as possible to the battery in the positive cable. Applicable codes may limit
how far the protection can be from the battery.
DC Cabling
Definition DC cabling includes all of the cables and connectors between
the batteries, the DC disconnect and over-current protection device, and the
inverter/charger.
Type All installations require multi-strand insulated cables. The DC
cables must be copper and must be rated 105 °C minimum.
Size and Length See Table 3 for required DC cable length, cable size and
required fuse size for the Freedom SW 3000. Wire size is usually marked on
the cables.
IMPORTANT: Using a smaller gauge cable or a longer cable may cause the
inverter to shut down under heavy load.

Unpacking and Inspecting the Freedom SW 3000 Inverter/Charger
HEAVY LOAD
The Freedom SW 3000 Inverter/Charger is heavy (see “Inverter/Charger
Physical Specifications” on page 40). The unit is too heavy for one
person to safely lift and mount. Xantrex recommends that two people lift
and mount the unit. Always use proper lifting techniques during
installation to prevent personal injury.
IMPORTANT: Keep the carton and packing material in case you need to
return the Freedom SW 3000 for servicing.
1.
Unpack the unit and check the materials list. If anything is missing
from the shipping box, contact Xantrex Customer Service. See
“Contact Information” on page i.
2.
Record the serial number of the Freedom SW 3000 and other purchase
information in the “Warranty and Product Information” section of the
Freedom SW 3000 Sine Wave Inverter/Charger Owner’s Guide. You
will be asked for this product information if you need to call Xantrex
Customer Service.
3.
Save your purchase receipt to use as proof-of-purchase. This receipt is
required if the inverter/charger should need warranty service.
4.
Save the original shipping carton and packing materials. If the
inverter/charger needs to be returned for service, it should be shipped
in the original carton. Packing the Freedom SW 3000 in the original
shipping carton is also a good way to protect the inverter/charger if it
ever needs to be moved.

Step 1: Choosing a Location for the Inverter/Charger
The inverter should only be installed in a location that meets the following
requirements:
FIRE AND EXPLOSION HAZARD
Ventilated
Do not operate the inverter/charger in a closed-in
area or restrict ventilation in any way. The inverter/
charger requires air circulation to maintain
optimum operating temperature and provide best
performance. If the unit has inadequate ventilation,
it may shut down due to overheating.
The air vented through the openings should also
have a path to circulate away from the inverter/
charger.
Dry
Do not allow water or other fluids to drip or splash
on the inverter/charger. Do not expose to rain, snow
or water.
Cool
Normal air temperature should be between
32 °F and 140 °F (0 °C and 60 °C)—the cooler the
better within this range.
Clearance
Allow as much space around the inverter/charger as
possible. Xantrex recommends that other objects
and surfaces be at least 3 inches (76 mm) away
from the ventilation openings for best performance.
This equipment contains components that could produce arcs or sparks.
To reduce the risk of fire or explosion, do not install this equipment in
compartments containing batteries or flammable materials, or in locations
that require ignition-protected equipment. This includes any space
containing gasoline-powered machinery, fuel tanks, or joints, fittings, or
other connections between components of the fuel system.
injury.
HEAT HAZARD
Do not cover or obstruct the ventilation openings. Do not install this
equipment in a compartment with limited airflow. Overheating may
result.
injury.
The location of the inverter/charger is a key factor in system performance.
Allow sufficient clearance around the unit (recommended minimum
3 inches (76 mm)) and install in a well-ventilated compartment to prevent
overheating and premature shutdown of the inverter/charger.
18
Safe
Locate the inverter/charger away from battery in a
separate well ventilated compartment. Do not
install the inverter/charger in any compartment
containing flammable gases or liquids like gasoline.
Close to
battery
compartment
The length and size of your DC cables will affect
performance. Use the DC cables recommended in
Table 3 on page 13. The unit should not be installed
in the battery compartment due to the possible
presence of explosive hydrogen gas from the
batteries.
Protected from
battery acid
and gases
Never place the inverter/charger directly above the
batteries—gases from battery will corrode and
damage the inverter/charger. If the inverter/charger
is installed in a compartment above the batteries,
make sure there is a solid, gas-impermeable wall
dividing the two compartments.
Never allow battery acid to drip on the inverter/
charger or its wiring when filling the batteries or
reading their specific gravity.
Orientation
To meet regulatory requirements, the Freedom SW
3000 must be mounted in one of the approved
mounting orientation. See Figure 3 on page 21.
975-0546-01-01
19
Step 2: Mounting the Inverter/Charger
Considerations
Before mounting the Freedom SW 3000, take the following two factors into
account.
1.
The weight of the inverter/charger requires two people to install it.
2.
Mounting considerations are shown in Figure 3 on page 21.
To mount the inverter/charger:
1.
Remove the inverter/charger from its shipping container.
2.
Verify that all components are present, and record relevant product
information on form WA-4 in the Freedom SW 3000 Sine Wave
Inverter/Charger Owner’s Guide.
3.
Select an appropriate mounting location and orientation. To meet
regulatory requirements, the Freedom SW 3000 must be mounted in
one of the orientations shown in Figure 3 on page 21.
HEAVY LOAD
4.
Mark the position of the mounting holes.
The Freedom SW 3000 Inverter/Charger is heavy (see “Inverter/Charger
Physical Specifications” on page 40). The unit is too heavy for one
person to safely lift and mount. Xantrex recommends that two people lift
and mount the unit. Always use proper lifting techniques during
installation to prevent personal injury.
5.
Pilot drill the six mounting holes.
6.
Fasten the inverter/charger to the mounting surface with six 1/4"–20
steel screws or bolts.

Step 3: Connecting the AC Input and AC Output Wires
AC Knockouts There are two dual 1.0"/ 3/4" trade-size knockouts on the
side panel for AC wiring. Use the same trade size of strain relief as the trade
size of the knockout(s) you are using.
Make sure wiring being connected to the inverter/charger is disconnected
(physically or by opening the breaker) from all electrical sources before
handling. All wiring must be done in accordance with local and national
electrical wiring codes.
AC Wiring Terminals The AC wiring terminals accept cables of a
specific size. See “AC Wiring” on page 11 for required sizes.
FIRE, ELECTRICAL SHOCK, AND ENERGY HAZARDS
injury.
General AC Wiring Considerations
AC and DC Wiring Separation Do not mix AC and DC wiring in the
same conduit or panel. Consult the applicable installation code for details
about DC wiring and AC wiring in vicinity to each other.
AC Input and Output Isolation The AC input and output circuits of this
inverter/charger are isolated from each other when in invert mode to ensure
safe operation. This isolation must be maintained in the installation, by
being sure not to connect AC input and output wiring to a common point.
For example, do not route the AC input and output neutrals to a common
neutral bus.

DC Connection Precautions
Guidelines for Routing the DC Cables
Follow these guidelines to ensure maximum performance.
ELECTRICAL SHOCK AND FIRE HAZARD
Route the cables away from sharp edges that might damage the
insulation. Avoid sharp bends in the cable.
injury.
•
•
•
•
28
Do not attempt to use the chassis in place of the battery negative
connection for grounding. The inverter requires a reliable return path
directly to the battery.
To reduce the chance of radio frequency interference, keep the positive
and negative cables close together—ideally, held together by straps,
loom, or insulated clamps at regular intervals.
To ensure maximum performance from the inverter/charger, do not
route your DC cables through a DC distribution panel, battery isolator,
or other device that will cause additional voltage drops. The exception
is the DC fuse and Disconnect or the DC circuit breaker which is
required at the battery to protect the DC wiring.
To help avoid damage caused by reverse polarity battery connection, it
is a good idea to mark each end of each cable to identify it as a positive
(red) or negative (black) cable before routing the wiring.
Connecting the DC Cables to the Inverter/Charger
FIRE HAZARD
Use only appropriately sized copper cable. Loose connections or
improper connections will overheat. Make sure the bolts supplied by
Xantrex on the inverter/charger are tightened to a torque of 15–16 ft-lbs
(20.4–21.7 Nm). Torque all other connections to the manufacturer’s
specifications. Make sure the DC cable, washers, and bolt are assembled
in the order shown in Figure 5.
injury.
EQUIPMENT DAMAGE DUE TO REVERSE POLARITY
1.
Route the DC cables from the battery bank to the inverter/charger.
Observe the “Guidelines for Routing the DC Cables” on page 28.
2.
Install a DC fuse and disconnect switch or a DC circuit breaker
between the inverter/charger and the battery. It must be installed in the
positive side of the DC circuit, as close as possible to the battery.
This protects your battery and wiring in case of accidental shorting.
See Table 3 on page 13 for required fuse or breaker size.
3.
Open the DC disconnect switch or turn off the DC circuit breaker.
4.
Connect one connector on the POSITIVE (+) cable to the POSITIVE
DC terminal on the inverter/charger, as shown in Figure 5. The
connector goes on first, then the flat washer (steel), lock washer
(steel), and 3/8" bolt (brass).
5.
Connect the other connector to the POSITIVE (+) terminal on the fuse
or breaker. Observe polarity carefully while completing the
installation.
Before making the final DC connection or closing the DC breaker or
disconnect, check cable polarity at both the battery and the inverter/
charger. Positive (+) must be connected to positive (+). Negative (–) must
be connected to negative (–).
975-0546-01-01
Use a wrench to tighten the bolt to a torque of 15–16 ft-lbs
(20.4–21.7 Nm) at the inverter/charger end. Observe the fuseholder or
breaker manufacturer’s recommendation at the other end.
6.
Connect one connector on the NEGATIVE (–) cable to the
NEGATIVE (–) DC terminal on the inverter/charger, as shown in
Figure 5. The connector goes on first, then the flat washer (steel), lock
washer (steel), and 3/8" bolt (brass).

7.
Before proceeding, check that the cable polarity is correct: POSITIVE
(+) on the inverter/charger is connected to the POSITIVE (+) on the
battery, and NEGATIVE (–) cable is connected to the NEGATIVE (–)
terminal on the inverter/charger.
IMPORTANT: The next step is the last cable connection you need to make.
A spark is normal when this connection is made.
8.
Connect the other end of the cable to the NEGATIVE (–) terminal on
the battery.
9.
Use a wrench to tighten the bolt to a torque of 15–16 ft-lbs
(20.4–21.7 Nm) at the inverter/charger end.

Step 5: Connecting the Battery Temperature Sensor (BTS)
Installing a battery temperature sensor (BTS) extends the life of a battery by
preventing overcharging in warm temperatures and undercharging in cold
temperatures. With a BTS monitoring the battery temperature, the voltage
delivered to the battery is adjusted according to the battery’s actual
temperature.
Connector
The BTS has a self-adhesive backing and attaches to the side of the battery.
A 25-foot (7.6 m) cable is supplied with the BTS.
Sensor cable
Mounting Options
You can mount the BTS in one of two ways:
•
•
Mounting the sensor to the negative battery post allows the internal
battery temperature to be sensed and provides the most accurate
results.
Attaching the sensor to the side of the battery using the self-adhesive
backing also provides good results in most situations.

Battery Information
Battery capacity Battery size or capacity is just as important as the
battery type selected for use with the Freedom SW 3000. The batteries are
the most important part of your system, so Xantrex recommends that you
purchase as much battery capacity as possible. A large battery will extend
running time and ensure that your inverter/charger delivers full rated surge.
Xantrex recommends a minimum battery size of 200 amp-hours (Ah)
for moderate loads (<1000W) and greater than 400 Ah for heavy loads.
Estimating Battery Requirements
Calculating Battery Size
Step 1: Compute Amp-hours
For each appliance, compute the number of amp-hours that will be used
between charging cycles, as follows:
1.
Obtain the wattage. If the wattage is marked on the nameplate rating,
use that. Otherwise, multiply the marked voltage and amperage:
WATTS = VOLTS × AMPS.
2.
Obtain the Watt-hours by multiplying that amount by the hours the
appliance will be used:
WATT-HOURS = WATTS × HOURS.
3.
Obtain the amp-hours that the appliance requires by dividing that
amount by 10 (the factor for the Freedom SW 3000, which is a 12-volt
system):
BATTERY AMP-HOURS USED = AC WATT-HOURS/10
See “Estimating Battery Requirements” for information on a more detailed
calculation.
About Amp-hours A number of different standards are used to rate
battery energy storage capacity. Automotive and marine starting batteries
are normally rated in cranking amps. This is not a relevant rating for
continuous loads like an inverter. Deep-cycle batteries use a more suitable
rating system such as amp-hours (Ah).
Amp-hour capacity is the number of amps a battery can continuously
deliver during a specified number of hours. It is represented by the product
of the two —amps multipled by hours.
A typical marine or RV battery rated for 100 Ah can deliver 5 amps for 20
hours (5A × 20 hours = 100 Ah). This same battery can deliver a higher or
lower current for less or more time, limited approximately by the 100 Ah
figure (50 A for 2 hours or 200 A for 1/2 hour), but usually the capacity
figure given is only accurate for the specified duration (20 hours).

For example, a 100 W light bulb that is used for 4 hours will use 400 watthours (Wh) and the inverter will consume approximately 40 Ah from a 12
volt battery.

Battery Bank Sizing
Battery Information
Size the batteries at approximately twice the estimated total amp-hour
usage. Doubling the expected amp-hour usage ensures that the batteries will
not be overly discharged and extends battery life.
Resist the temptation to skip this doubling step. More capacity is better
since you will have more reserve capacity, be better able to handle large
loads and surge loads, and your battery won’t be discharged as deeply.
Battery life is directly dependent on how deeply the battery is discharged.
The deeper the discharge, the shorter the battery life.
Troubleshooting If you find that the system shuts down when appliances
with large motors are started, the problem may be that this motor is too
much for the battery. Even though you calculated the amp-hour
requirements appropriately, the startup of a large motor makes high
demands on the battery. You may find that adding more amp-hours (in the
form of extra batteries or replacement with a bigger battery) solves the
problem.

This example illustrates how quickly your battery needs can escalate. To
reduce the required battery bank size, you can either conserve energy by
eliminating or reducing the use of some loads, or recharge more frequently.

Battery Banks
Restrictions on Motor Size
As your power requirements increase, you may need to use more than one
battery to obtain sufficient capacity. Batteries can be connected in parallel,
in series, or in series-parallel to create higher capacity systems.
An appliance may require three to six times its normal running current in
order to start. The Freedom SW 3000 can handle surges to 6000 watts for
ten seconds, which translates to a locked-rotor-amp rating of no more than
50 A. The locked rotor amp may be specified on the motor nameplate as
“LRA” or “LRI”.
See “Cabling and Hook-up Configurations” on page 45 for more
information about battery inter-connection schemes.
Mixing Batteries Batteries connected in parallel should be of the same
type and amp-hour rating and from the same manufacturer.
It is not recommended to connect batteries of different types, amp-hour
ratings or manufacturers. Improper charging and decreased battery life will
result.
Battery Bank Sizing Worksheet
The following worksheet is a guide to help you determine your battery
needs. Be generous in estimating the time for which you will run each of the
loads to ensure sufficient battery capacity.
975-0546-01-01
When considering appliances with large motors, follow these guidelines:
•
•
Make sure that the motor’s LRA rating is no more than 50 A. The
Freedom SW 3000 may not be able to start a motor with a higher LRA,
and the Freedom SW 3000 will shut down if the attempt is made.
Make sure the battery bank, DC cables and DC fuses are capable of
handling up to 600 A DC for ten seconds. A weaker circuit may not be
able to provide sufficient power to the Freedom SW 3000 to allow the
Freedom SW 3000 to start up the appliance. Again if the circuit cannot
deliver the required current, the system may shut down or the fuse may
open.

Cabling and Hook-up Configurations
To make a larger battery bank, connect individual batteries with heavy
cables. The actual size of the cable depends on whether the batteries are
connected in parallel or series. Generally, the cable should not be smaller
than the inverter cables—if the main cables are 4/0 AWG, the battery
interconnects should be 4/0 AWG.
Parallel Connection
Batteries are connected in parallel when all the positive terminals of a group
of batteries are connected and then, separately, all the negative terminals are
connected. In a parallel configuration, the battery bank has the same voltage
as a single battery, but an Ah rating equal to the sum of the individual
batteries. See below.
The best configuration is to connect the batteries in series and parallel. This
requires additional cables, but reduces imbalances in the battery bank and
can improve the overall performance. Consult your battery supplier for
more information regarding the hook-up configuration required for your
system.

Several smaller batteries can be connected to create a battery bank of
substantial size. You can connect batteries in three ways: in parallel, series,
or series-parallel.
Series Connection
When batteries are connected with the positive terminal of one battery to
the negative terminal of the next battery, they are connected in series. In a
series configuration, the battery bank has the same Ah rating of a single
battery, but an overall voltage equal to the sum of the individual batteries.
See below.

Series-Parallel Connections
As the name series-parallel implies, both the series and parallel
configurations are used in combination. The result is an increase in both the
voltage and the capacity of the total battery bank. This is common with all
battery-inverter system voltages. The smaller, lower voltage batteries are
first connected in series to obtain the necessary voltage, and then these
“batteries connected in series” sets are connected in parallel to increase the
battery bank capacity. See below.
